Vince Gill and Amy Grant have a love story that few can write. Both were married to other people when they met, but admit that their first meeting in 1993 was love at first sight.

“I think that a part of me loved him instantly,” Grant says. “I felt like I knew him instantly. I was so moved by him as a human being that I went up behind him and just hugged him as hard as I could while he was singing. I just said, ‘I just needed to hug you all night.'”

Gill was so inspired after meeting Amy Grant that he wrote his hit song “Whenever You Come Around.” At a show at the Ryman, Gill gave some of the back story, saying, “This is a song that was inspired by a smile that I saw for the first time on the face of a woman that I’d never met. That was Amy Grant back in 1993.

“I was so inspired, moved by the sight of that smile, that I came home and wrote this song,” he added.

The couple remained adamantly faithful to their spouses but admit that their minds were constantly on each other.

While the couple didn’t marry until 2000, this clip from a Christmas with Vince Gill concert from 1993 shows undeniable chemistry between the two. During the Tulsa concert, Gill joins Grant to sing “Tennessee Christmas”, a song Grant recorded on her first Christmas album in 1983. See the video below.
